Before a lot goes on sale, a sample goes to an independent laboratory. The lab confirms the compound’s identity by mass spectrometry, measures its purity by HPLC and reports how much peptide is actually in the vial. Many lots are also tested by Janoshik Analytical, including blind tests and endotoxin screening. Every link below opens the lab’s own copy of the report, so you can check it hasn’t been edited.
To find the certificate for your vial, search for the lot number on the label (it starts with JP) or the product code, such as RT10. Can’t find your lot? Message us on WhatsApp and we’ll send you the report.
